improve doctest coverage in schemes/homset.py

[aghitza]

The current coverage is 8% and should be brought up to 100%.

Also, there are small but annoying bugs such as: the methods that enumerate the points on schemes over finite fields do not sort the list before returning it (this issue is addressed by #9055).

Depends on #11599
